Re: Hogwash

The Oxford English Dictionary gives this
definition for the original and literal sense: "The swill of a brewery or kitchen
given to hogs: pig's-wash." First quotation illustrating that sense is dated c.
1440. For the figurative sense, the OED says "Contemptuously applied to weak inferior
liquor or any worthless stuff." First quotation for that sense is dated 1712:
"Your butler purloins your liquor, and the brewer sells you hogwash" (Arbuthnot).
